Sheet Pan Cajun Shrimp Fajita Recipe FAQs
How do I know if my shrimp is fresh and good for this recipe?
Look for shrimp that’s firm to the touch with a mild ocean scent—not fishy. Fresh shrimp should have translucent flesh without dark spots or a slimy texture. I recommend buying peeled and deveined shrimp labeled “fresh” or properly thawed if frozen.
Can I store leftover Sheet Pan Cajun Shrimp Fajita in the fridge, and for how long?
Absolutely! Place leftover shrimp and veggies in an airtight container and store in the refrigerator for up to 3 to 4 days. Keep your tortillas separately to prevent sogginess. Just reheat gently so you don’t overcook the shrimp.
What’s the best way to freeze this shrimp fajita for later?
Very! Freeze the cooled shrimp and vegetables in airtight, freezer-safe containers or heavy-duty zip-top bags for up to 3 months. When ready to enjoy, thaw overnight in the fridge. Reheat in the oven at 350°F for 10–15 minutes or microwave in short intervals to preserve texture and flavor.
My shrimp sometimes turns rubbery when I roast it. How can I avoid that?
This is common but easy to fix! Make sure not to overcrowd the pan, letting each piece roast rather than steam. Stick to the 12–15 minute roasting time at 425°F and pull the pan out as soon as the shrimp turn pink and firm. Overcooking squeezes out moisture, leading to that rubbery bite.
Are these Cajun shrimp fajitas safe for pets if I want to share?
I’d advise against it. The Cajun seasoning contains spices that may upset your pet’s stomach, and shrimp seasoning often includes garlic or onion powder, which are toxic to dogs and cats. Always keep spicy and seasoned foods for human enjoyment only, and offer your furry friends pet-specific treats instead!
